Heller said, there is a clue in the last minutes of season 6 episode 1. I saw something, which wasn't mentioned here before:

Right before Lisbon entered the house a car went by. She looked after it but then she heard a noise from inside the building. Then she got a call from Jane. He left her a message. Here is the thing: Jane was also sitting in a car. And I wonder why he was smiling as he asked her where she might be. As if he knew... Maybe he was the one, who drove by.


What do you think about this "Car Theory"? Please comment.
